PORTABLE GRAIN-DUMP.

SPECIFICATION forming part of Letters Patent No. 756,578, dated April 5,1904..

Application filed May 4., 190s. serial No. 155,516. (No model.)

To @ZZ whom it may concern.:

Be it known that I, JOSEPH E. CAMP, a citizen of the United States,residing at Washington, in the county of Tazewell and State of Illinois,have invented certain new and useful Improvements in PortableGrain-Dumps; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

This invention pertains to an improved portable grain-dump of that`class on which wagons are driven and raised at one end to deliver theirloads.

The obj ect of the present invention is to furnish a simple, light, anddurable machine which can be easily transported from one place toanother.

A further object is to provide carryingwheels for a grain-dump by whichit may be more readily moved about.

Another object is to provide a tongue for the dump for assisting intransportation, and, furthermore, an object also is to provide a devicefor locking the wagon against movement while on the dump, all of whichwill' be clearly pointed out in the following description and in theaccompanying claims.

In the drawings presented herewith, which form part of my application,Figure l is a rear elevation of the dump. Fig. 2 is a front view indetail of a ratchet mechanism and bandbrake device. Fig. 3 is a sideelevation of the machine, showing the carrying-wheels resting in anexcavated place for allowing the platform of the device to rest firmlyupon the ground. Fig. A is a perspective view of a casting for carryingcertain gear-wheels to be described. Fig. 5 is a perspective View of aportion of the dump, showing a platform on which the forward wheels of.the wagon are carried.

A indicates a sill, one of which is placed at each end of the machineand upon which is securely fastened the floor-boards B B, at each sideof which are the approaches C O, as indicated in Fig. 3. Upon each endsill A is erected a pair of posts D D, which, together with a topcross-piece E, form a frame braced by tie-rods E, as shown, the samebeing bolted to the approaches C. Secured on the top of one of theframes thus constructed is a pulley F for receiving a cable. In Fig. lis shown another pulley H, secured to the sill A, which also takes thecable Gr in the manner shown. The cable passes under the platform andruns over a pulley H' at the opposite side of the machine and thence upto a drum I on a shaft J having bearings near the top of the frame, asin Figs. 1 and 3. Said shaft J carries at its outer end tworatchet-wheels K L, both being aflixed thereto, their teeth extending inthe same direction. Adjacent to the ratchet L is a wheel M, loose on theshaft J and held by means of a band N, which nearly surrounds it. Thetwo ends of said band are connected to a lever O, pivoted on a bracketP, secured to one of the posts D, as shown. It will be seen that theends of the said band are secured at opposite sides of the pivot of thelever. By moving the lever in one direction the band is tightened, andwhen moved in the opposite direction it is loosened. In Fig. 3 at Q, isan arm secured to D, behind which the lever is thrown when the band istightened to hold the wheel M from moving. Next to the ratchetwheel K onthe shaft is a lever R, having a pawl S to engage the teeth of saidwheel K, a spring T serving to keep the pawl in constant engagement withsaid teeth. On one of the spokes of the brake-wheel M is a pawl U, heldby a spring V into the teeth of the wheel L. Beneath this portion of theapparatus, near the bottom of the dump, is a casting W, (shown in Fig.47,) in the upper portion' of which is carried a gear-wheel 2, to whichis connected a pitman 3, the upper end having pivotal connection withthe lever R. Meshing with the gear 2 is a pinion-gear 4, driven by powerof any kind by means of the shaft 5.

In Fig. 5 is shown the platform for raising the forward endof the wagon.This consists of a plank 6, resting upon the end sills A, with a cleat 7at each end and abeam 8 at each side of the plank acting as stops forthe wheels. The platform is adapted to rise and fall by means of thecable G at one end, which is attached to a bail 9, Fig. 5, and at theother end a bail l0 is employed, to which a cable 11 is attached, whoseother end is adapted t0 IOO wrap upon the drum I, said cables G and 11being wrapped upon the drum so as to wind in the same direction ofnecessity. Power applied to the pinion 4 transmits motion to the gear 2and a consequent reciprocating movement `to the lever R. Such movementwill move the ratchet-wheel K a portion of a turn and will in turnrevolve the windingdrum I and take up the cables. As eachpartial turn ofthe ratchet-wheels is taken the pawl U of the wheel M holds theratchetwheel L and the drum I from retrograde movement. During this timethe band-brake is set so that the wheel M cannot revolve, as will beunderstood. The front wheels of the Wagon are driven upon the platformand rest between the beams 8, which serve to hold said wheels in place.

I provide a tongue for the machine, (indicated at 12,) on the forwardend of which is pivoted a bar 13 by means of an upwardlyextending arm14. This portion of the apparatus is designed to receive the weight ofthe rear of the wagon for preventing movement thereof during the dumpingoperation, said .bar 13 receiving the rear aXle against its end.

The lock thus provided may be operated aus tomatically by being met bythe end of the wagon-box, as indicated, or may be raised by hand orother means, as desired. The tongne being located at the middle of thedevice is not inthe way of the horses or the wheels of the wagon andserves to draw the dump from place to place and at the same time servesas a support for the lock described.

An important feature of my improved dump is the provision fortransporting the machine by means of carrying-wheels A', one of which isplaced at each end of the platform, as having support on the sills Adescribed. rIhese when resting on the surface of the ground support themachine well above the uneven places in traveling over the field, sothattransportation is readily accomplished. When setting the dump 'for use,the earth is removed from beneath the wheels, so that those members willbe let down to permit the sills A to rest firmly upon the ground, asshown in Fig.

3, in which position the dump is firm andv ready for use with no furtherpreparation. When moving the dump, the horses are attached to the tonguein the usual way and driven to the next location or wherever it isdesired to take the device, the wheels A raising the dump from theground as they are drawn out of the depression made for them. When theplatform 6 is raised, as shown in broken lines, and the wagon is to belet down after being dumped, the lever O is drawn from behind the stopQ, there being sufficient play in the pivot thereof to permit suchmovement, and the band is slightly loosened, so that the Wheel M mayturn withv the shaft J as the weight of the platform revolves the drumI, all of which will be understood,

I am not aware of a portable grain-dump having a tongue for transportingit, much less a tongue having the automatic locking device for the rearof the. wagon, as described; neither a'm I aware of a dump of this .kindhaving wheels for transporting purposes, nor is there to my knowledge adevice constructed as to the other portions of the operating mechanism,and therefore I claim- 1. A grain-dump comprising a platform adapted torest on the ground while in use, carrying-wheels for said platform bywhich it is made portable, a draft device for transporting purposes, avertically-movable platform carried by the first platform and meansl forraising and lowering the same for the purposes herein set forth anddescribed.

2; A portable grain-dump comprising a platform for supporting the frontwheels only of a wagon to be dumped, said platform resting upon theground a second platform upon the first the same being adapted to riseand fall for carrying the said wheels of the wagon, cables attached tothe platform, a windingdrum for the cables and means for operating thedrum to lift the platform for the purposes set forth and described.

3. A portable grain-dump comprising a platform B adapted to rest on theground, carrying-wheels Al for the same, a tongue 12 attached to saidplatform by 'which it may be transported and an elevating-platform 6forv raising the front end of a wagon to be delivered of its load, and alocking device on the ,tongue 12 by which the rear of the wagon isprevented from moving while in the dumping position.
